Inhibition of adenylyl cyclase 1 or exchange protein activated by cAMP restores ATP‐sensitive potassium channel activity after chronic opioid exposure

Key Points

• The study aims to explore AC1 inhibition as a potential target for addressing opioid tolerance and withdrawal effects.
• Investigated the role of adenylyl cyclase 1 (AC1) in opioid signaling.
• Assessed the impact of EPAC activity on potassium channel function.
• Analyzed changes in potassium channel activity in response to chronic opioid exposure.
• Inhibition of AC1 increased EPAC activity.
• Restoration of ATP-sensitive potassium channel activity was observed after chronic opioid exposure.
• Improvements in potassium channel function suggest potential pathways for mitigating opioid tolerance.
